ASTM A516 plates API Std 650 low-alloy steel tanks

Under the same sealing effect, the internal API Std 650 low-alloy steel tanks floating roof API 650 tank can further reduce the evaporation loss compared with the external floating roof API 650 tank. This is due to the shielding of the fixed roof and the gas phase layer between the fixed roof and the inner floating plate, which has more significant heat insulation effect than the double disc floating roof of the API Std 650 low-alloy steel tanks external floating roof tank.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API Std 650 low-alloy steel tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

Atmospheric API Std 650 low-alloy steel tanks inspection includes annual inspection and comprehensive inspection. Annual inspection is an inspection during operation to ensure the safety of atmospheric storage tanks during the overhaul period, at least once a year. Comprehensive inspection is a more comprehensive inspection of atmospheric storage tanks according to a certain inspection cycle. The inspection content of metal atmospheric API Std 650 low-alloy steel tanks includes the safety management of the storage tank, the inspection of the tank body and its operating conditions, etc.
